Propagation Loss in Crystalline Silicon Photonic Waveguides Due to Gamma Radiation
Abstract
Silicon photonics has been demonstrated to have application in high data capacity scenarios. It would be desirable to use such technology in harsh environments where gamma radiation may be present, such as space or high energy physics experiments. In this article, the effect of such radiation is studied for passive silicon photonic waveguides. We demonstrate a correlation between optical power overlapping with the waveguide core/cladding interface and show that partially etched rib waveguides are less sensitive to performance degradation as a function of waveguide geometry. Additionally, we show that the post-exposure performance of these waveguides can be improved through heat treatment.
